Ferries now ten years in the service of science: How FerryBoxes explore the oceans
A great deal of time and money can be saved if autonomous measuring devices for the monitoring of water quality are installed on vessels with fixed routes. These are primarily ferries and cargo ships.
Working in cooperation with other European scientists, coastal research scientists at the Helmholtz-Zentrum Geesthacht (HZG) have taken up this idea and developed the FerryBox system. The first FerryBox was installed ten years ago on the ferry operating between Hamburg and Harwich (England).
The company 4H Jena has worked with these scientists to develop the system into a marketable product. The Box is equipped with different instruments depending on the field of interest and particular requirements: from a thermometer, to devices for monitoring algal growth, to pH sensors for the measurement of ocean acidification.
A FerryBox costs between 60,000 and 100,000 euro – depending on the equipment installed. In comparison: the deployment of a small research vessel costs approx. 10,000 euro per day.
Research on the FerryBox
The cargo ship LysBris has a FerryBox onboard and is oparating on a fixed route between England and Norway (photo: HZG).
FerryBoxes are, however, also installed on research vessels and permanent monitoring stations such as observation poles, or in on-shore research containers. At present the HZG has five boxes in operation in the German Bight.
Dr. Wilhelm Petersen, who is leading the research on the FerryBox, explains: “Such long-term measurement series with this high degree of temporal and spatial resolution are extremely important for our science. One example is for the observation of algal blooms, which often take only one or two weeks.”
As it is improbable that a research vessel will pass by just at the time when algal bloom occurs. A further advantage: the cargo ships and ferries operate in almost every type of weather, so that there are hardly any data gaps. The measurement data are transferred to Geesthacht via a mobile phone network or satellite communication and are immediately available on the Internet to all scientists worldwide.
Wilhelm Petersen and his colleagues at the Institute of Coastal Research are presently working on the development of new measuring devices for the FerryBox. These include, among others, sensors for the measurement of nitrate, ammonium, phosphate and silicate.
The measurement of these nutrients helps scientists to provide evidence on marine pollution and gain a better understanding of biological correlations in the ocean; for instance, the occurrence of algal blooms, their dynamics and species composition subject to nutrient input. The sensors are to be installed in the North Sea in the course of this year.
The FerryBox is ten years old: an occasion to celebrate its success in a film
The head of the Public Relations department at the Helmholtz-Zentrum Geesthacht, Dr. Torsten Fischer, commented: “The challenge for us was to portray a down-to-earth technical device in a lively way.” The result is an eight minute film which gives the coastal research scientists behind the FerryBox an opportunity to say a word and yet also explains the scientific and social relevance of this measuring technology in a detailed and understandable way.
The film “FerryBox – when ferries become research vessels” can be viewed on the Internet site YouTube, and can be used by online editorial departments on the Internet.
Background to the FerryBox
The activities of the HZG in the German Bight are supported by the shipping companies DFDS and Cassen Eils GmbH & CO KG, who have provided space on their vessels free of charge for the operation of the installations.
